Sampling and Reconstruction of Sparse Signals

 

Speaker:

Prof. Dr-Ing. Volker Kühn (University of Rostock, Germany)

Content

In the last two decades the pervasion of our daily life by communication and multimedia devices like smart phones, digital cameras or MP3 players grows at increasing speed. The basic foundation of all devices is digital signal processing, especially the representation of analog signals by bits and bytes. In order to keep storage and data rate requirements at a moderate level, compression is an inevitable part of digital systems. It removes redundant parts from the signal and represents these signals with as few bits as possible. Thereby, lossy and lossless compression are distinguished. We call compressible signals as being sparse.

 

Conventional strategies first sample the analog signal at high rate according to Shannon's famous sampling theorem and compress it afterwards. This provokes the question why the sampling process itself cannot directly perform the compression in order to avoid costly sampling at high rate. In order to answer this question, the lectures will give an overview of state-of-the-art sampling techniques and will focus on two different approaches.

 

The first part will introduce a technique called 'Compressed Sensing' allowing to compress sparse signals in a very efficient way. After discussing some toy examples to illustrate the underlying problem, the compression and its fundamental properties are introduced. Next, the reconstruction step is explained for one simple exemplary algorithm, the Orthogonal Matching Pursuit (OMP) algorithm.

 

In the second part, Shannon's famous sampling theorem will be revisited first. Next, the class of analog Finite Rate of Innovation (FRI) signals will be introduced which can be sampled at rates much lower than stated by Shannon. For reconstruction, the annihilating filter as one example of spectral estimation algorithms will be presented. Finally, this approach is applied to Particle Image Velocimetry as one possible example.

Last Generation of Multicore Video Decoders

Speaker: Prof. Dr. Wassim Hamidouche (INSA Rennes, France)

Dr. Wassim Hamidouche received the Engineering Degree in Computer Science from the University of sciences and technologies of Algiers, Algeria, in 2006 and the Master Degree in electrical engineering from the University of Poitiers, France, in 2007.

He received Ph. D. Degree in Signal and Image Processing from the University of Poitiers, France in 2010. From 2011 to 2012 he was a

Research Engineer with Canon Research Centre, Rennes, France, where he worked on video compression standard High Efficiency Video Coding (HEVC) and its scalable extension SHVC.

From 2013 to 2014 he joined as Post Doc the IMAGE group, IETR laboratory, Rennes, France.  Since 2015 he has been an associate professor at INSA Rennes and member of the IMAGE group, IETR Institute. His main research interests are related to image and video compression,multimedia transmission over wireless networks and security of multimedia contents. He is an author of more

than 46+ conference and journal papers. He has also been involved in several research collaborative projects: CAIMAN(ANR), 4EVER, H2B2VS (Celtic-Plus) and leader of two projects: 4EVER-2 (FUI), and 4KREPROSYS (Celtic-Plus).

Abstract

With the dramatic increasing of multimedia applications and video coarse consumption, content quality evaluation has become a new exciting and challenging topic. Recently, a new coding tools, called JEM, has been developed with the main goal to provide a bit rate saving up to 30% compared to HEVC. In this paper we present a performance comparison between the JEM and HEVC (HM) reference software, through an objective-based measurements and a deep experimental subjective quality assessment.

A set of video sequences, in two spatial resolutions High Definition (HD) and Ultr-High Definition (UHD), have been used in this study. Videos are encoded using both JEM and HEVC reference software. Results therefore have shown that JEM codec enables, subjectively, a bit rate saving of about 40% for the same perceived quality at low bit rate. objective-based comparison has demonstrated that JEM enables a bit rate saving up than 35% compared to the HEVC reference software. However, at high bit rate, the HM reference software enables a high video quality and reaches the quality of the video coded with the JEM codec.

Git: Basic principles and use

Speaker: Prof. Dr. Karol Desnos (INSA Rennes, France)

Karol Desnos is an Associate Professor at the National Institute of Applied Science (INSA) of Rennes. He holds a joint appointement at the Institute of Electronics and Telecommunications of Rennes (IETR). He obtained his PhD in Signal and Image Processing from the INSA Rennes in 2014. This work was co-supervised by the Pr. Jean-François Nezan and Dr. Maxime Pelcat from the IETR, and by Dr. Slaheddine Aridhi from Texas Instruments, France.

His research interests focus on dataflow models of computation and associated implementation techniques for the rapid prototyping of applications running on heterogeneous MPSoCs. In particular, his Ph.D. thesis focuses on the memory characterization and optimization of dataflow applications on MPSoCs. Since 2011, he contributes to the development of the PREESM open-source rapid prototyping framework.

Karol Desnos co-authored more than 20 articles in peer-reviewed international journals and conferences. He has served as a member of the technical program committee of 3 international conferences (SiPS, DASIP, ASR-MOV). He has been actively involved in several projects including H2020 Project (CERBERO), French ANR Projects (COMPA, ARTEFACT), U.S. NSF Project (COMPACTS-SL-MODELS), and a young researcher project funded by the French research society "GdR ISIS" (MORDRED) which he leads. He took part in the creation of the MTAPI standard with the Multicore Association.

In Fall 2012, Karol Desnos was a visiting researcher at the University of Maryland in the DSPCAD research group led by Pr. Shuvra Bhattacharyya. Since 2015, he has given invited lectures at INSA Euromediterranee (Fès, Morocco), at Universidad Politecnica de Madrid (Madrid, Spain), and at University of Rennes 1.

Abstract

When working on a group project, using an efficient system for sharing files is often key to success. Unfortunately, the most commonly used means of file transfers (e-mails, USB drive, synchronised folders, smoke signals...) are not very well suited for intensive file exchanges, even in a small group. Moreover, with such systems, it is difficult to keep track of the evolution of the project, which makes it very difficult to find the origin of a bug in project. The purpose of Concurrent Versioning Systems (CVS) is to offer file sharing systems specifically design for the simultaneous work of many developers on a common project.

Content

In this seminar, the basic concepts of the git versioning system are introduced, assuming no prior knowledge on any versioning system. After presenting the motivations for using a versioning system, the basic mechanics behind git will be introduced both conceptually, and through the illustration of tool commands. A quick comparison of git with other Concurrent Versioning Systems (CVS), a presentation of tools and website based on git, and a set of good practices for git users conclude this seminar. Concepts presented during the lecture will be put into practice during a lab.
